It's absolutely hilarious when people comment vague things like 'This is amazing! Thank you for sharing.' or 'Nice and inspirational post.' I don't know whether to laugh or cry. If you go to their profiles and check out their comment section, it's 95% of the time the same stupidly optimistically written comment on several posts.
If only people realise that writing a well-thought-out comment that adds something of value is infinitely better than copy-pasting, they might have a better chance at success here.
